(2005) Single camera 3D planar velocity measurements using imaging fibre bundles and two frequency Planar Doppler Velocimetry (2nu-PDV). In: Proceedings of the 17th International Conference on Optical Fiber Sensors, 23-27 May 2005, Bruges, Belgium. Proceedings of the SPIE, Volume 5855, pp. 924-92797808194585510277-786Xhttp://dx.doi.org/10.1117/12.624389http://dspace.lib.cranfield.ac.uk/handle/1826/74043D planar flow-field measurements are made using multiple imaging fibre bundles to port different views of the measurement plane, defined by a laser light sheet, to a CCD camera. The Doppler frequency shifts of particles entrained in the flow are transduced to intensity using an iodine absorption cell. Only a single CCD camera is used eliminating the pixel matching problem. Two optical frequencies generated from the same source are used sequentially to provide a reference and signal image.Planar Doppler VelocimetryPDVDoppler Global VelocimetryDGVacousto-optic modulatorsimaging fibre bundlesConference paper
